Ghost 'n Goblins (Capcom) PCB repairs

I received this board as part of an untested Romstar kit.
The board is manufactured by Capcom and has a Romstar paper label on the
board.

This is the first PC board I've seen with NO VISIBLE traces.
This will be a challenging repair! It looks much different than the other
Ghost 'n Goblins boards I've seen. The picture below shows what the PCB
looks like. Click the image for a 640x480 view.

Pin 9 on prom at 2E was bent and not making connection in the
socket. I fixed that with the needle nose pliers, being very careful not to
break off the pin, and reseated the chip in its socket. When I plugged in
the board I still got garbage on the screen. I grabbed my logic probe to see
if all the chips were running. Every chip I probed on the top PCB with the
card edge connector seemed to be running. I started to turn the board over
and set it on the ribbon connectors that join the two boards. When I did this
I noticed the startup sequence on the monitor. Could it simply be a poorly
seated ribbon cable? I powered down the board and reseated all the ribbon
cable connections. When I powered it back up I had a working Ghosts 'n Goblins
board.
